안녕하세요… Thanks for your question. Yes, you’re right that 안 should be placed directly in front of 해요 for verbs. In regards to your comment, 해요 is usually a verb (**하다) and for verbs, you put 안 right in front of 하다 or 해요. For example, ‘to study’ in Korean is 공부하다 (Gong Bu Ha Da) and you can say 공부해요 (Gong Bu He Yo) as “I study.” To make this sentence to “i don’t study” then you say, 공부 안 해요. Like you said, put 안 in front of 해요. This is because 공부하다/공부해요 is a verb. But, 피곤해요 is an adjective, coming from ‘피곤하다’ (Pi Gon Ha Da). If you want to make this sentence negative( making adjective sentence negative), 안 should be placed in front of the whole 피곤해요. Another example for adjective can be 미안해요 (I’m sorry.) 미안해요 comes from 미안하다 which is an adjective. To say, “i’m not sorry” you say 안 미안해요. Put 안 in front of whole 미안해요. Well, you can say 피곤 안해요 or 미안 안해요 but people will still understand what it means but will find a bit weird to say.

Since this Korean tutorials are meant to be just learning simple phrases, I don’t mention any grammars at all here. Hope you don’t find my explanation too overwhelming with grammar stuff. Please let me know if you still have any questions. Thanks!

Ah thank you so much for the clarification. I didn’t know about the difference between verbs and adjectives in the way the 안. is placed It has also always been hard for me to differentiate between verbs and adjectives, but now I understood a little more.
